Frequently asked questions
How many lumens does a living room need?
A living room is usually comfortable at 100–150 lux. In a 16 m² room that means roughly 1,600–2,400 lumens in total, counting all the lights. The exact value also depends on the ceiling height and the colour of the walls. The full table
What IP rating do you need in a bathroom?
Close to the bath and shower (zones 1 and 2) you need at least IPX4 — in practice an IP44 light; inside the bath or shower tray itself (zone 0), IPX7. There is no specific requirement for the rest of the bathroom, but in a humid room IP44 is a sensible choice there too. IP codes explained
Which light colour (kelvin) suits a home?
For relaxing — living room, bedroom — warm white, 2,700–3,000 K, is the familiar and comfortable choice. Where precise work happens (kitchen worktop, bathroom mirror, desk), neutral 4,000 K helps. Cool 6,500 K light usually feels too harsh in a home.
Which bulb base does my light need?
The most common are the large E27 screw and the small E14 screw; spotlights typically use the two-pin GU10 (230 V) and GU5.3 (12 V). The base is always listed on the light's data sheet — and in our shop you can filter every product by it. Bulb base identifier with pictures
